Be it known that I, PHILIP ADIson, a. subject of the Czar of Russia,an'd a resident of the city of New York, borough of Manhattan, in thecounty and State of New York, have invented a new and Improved Moldingor Conduit forT Electric Wiresyof which clear, and Aexact de thefollowngis a] scription. n

This invention relates to moldings or conduits for inclosing electricwires for systems of interior and exterior wiring, and 1t relates moreparticularly to conduits of that tvpe consisting of a trough or 'basesection.

for receiving the wires and a cover section having side flanges thatspring or snap over the sides of the trough 4Sectio The principalobjects of the present invention are to improve the construction ofconduits ithe character referred to by providing on the sides of thetrough or base section longitudinally-extending iianges with which thecover. section engages, the said anges being set inwardlyfrom the sidesof the base section, so that the covers'ection will be considerablynarrower than the base' section, whereby the sides of the latteroverhang the cover and the water dripping down the saidpsides of thebase section will have no chance to enter the joint between the twosections and interfere with'the electric wires within the conduit.

AdditionalV advantages are that the conduit is of comparatively simpleand inexpensive construction and the sections are so designed that theycan be connected as easily and quickly as could the sections in the oldform of conduit.

With these objects in view, and others l"as will appear as thedescription proceeds, the invention comprises various novel features ofconstruction and arrangement of parts which will be more fully describedhereinafter and set forth with particularity in the claims appendedhereto.' f

In the accompanying drawing which illustrates an embodiment of theinvention, and

wherein similar reference characters are employed to designatevcorresponding parts throughout the several views, Figure l isaperspective view of a portion of 'a conduit with' the sectionsinterlocked; Fig. I2 is a transverse section thereof; Fig. 3 is a 'clanview, partly broken away, of a cross union or coupling; Fig. 4 is a sideview of Fig. 3

"andl'Fig: 7 is an end view of Fig. 6. f

A designates 60 Referring to the drawing, the base section of ajstraightportion or of a couplingl ofthe improved conduit, such conduit being'made preferably entirely 'of metal and the base section'is intransverse cross-section. approximately elliptical, that isto say, thebase section A consists of a Hat portion 1 and semi-circular sideportions 2 and 3, there being'an open channel 4: oppo- -site the bottomportion 1, so that the electric wires can be placed in the base sectionlA. 7o

The bottom 1 of the base section A is pro vided with" perforations 5 forreceiving screws or equivalent fastenings whereby the base sectioncanwbe secured to a ceiling or wall or any other support. The sides 2and 75 3 are formed with lianges 6 which extend they full length of thebase section,l and` these flanges are -setinwardly considerably from theoutermost portions of the sides 2 and 3. Applied to these flanges is acover 80 section B which is formed'with longitudinal side flanges 7 thathave their internal surfaces concave to snap over and interlock with theconvex outer surfaces ofthe flanges 6 on the section A. The side members2 and 85 sections A and B the cover section B is 90.

placed in the position shown by dotted lines, Fig. 2, and thena'pressure is applied to the cover section in a direction toward thevbase section A, whereby theianges 6 of,

the latter yield toward each other to permit the flanges 7 of the coversection to-snap over the curved portion of the flanges 6. This manner ofassemblin is necessary in connecting the parts of t e couplings or vumons together, but in the case of the straight section of the conduit,as shown in Fig. l, the two sections can be asseml bledV together by arelativev longitudinal movement after 'the ends of the two sections arebrought into co erative relation. It

will be observed that t e outermost portions of the sides 2 and 3 of thebase section A overhang the sides of the cover section sovthat water on'the sidesof the base section Will drip ofi without entering the jointbetween the .two sections. Another advantage of providing the flanges 6is that greater of an elbow coupling;

resiliency is provided whereby the sections can be more easily andquickly connected. From the foregoing descrip-tion taken in connectionwith the accompanying drawings.' the advantages of the construction andmethod of operation and of the device shown will be readily understoodby those skilled lin the art to which the invention appertains, andwhile I have described the principle of operation, vice 'which I now.'consi er to be the best embodiment thereof, I desire to have itunderstood that the device shown is merely illustrative, and that suchchanges may be made when Ydesired as arelwithin the scope of theappended claims.

Having thus described my invention, I claim as new and desire to secureby Letters Patent: y

1. A conduit for electric conductors comprising a base sectonand a coversection, said base section consisting of a sheet metal structure formedwith a base; side members connected with the baseland yieldable towardand from each other, the edges of the side members being bent inwardlytoward each other and each terminating in a flange, said flanges beingsubstantially parallel with each other and 'extending outwardly awayfrom the said base and being disposed both inwardly from the sidemembers and the together with the de- -the opening, .and flanges onflanges,

flanges being oppositely curved;` and the cover se on wholly outside thebase section and consisting of a sheet metal piece of less width thanthe base section and having sub- 2. A metallic conduit comprising abase` and a cover-section, the base section being wider than the coversection and the base section having an opening throughout its length toreceive electric conductors, outstanding langes formed along the edgesof the cover section spaced apart ,a greater distance than the liangesof the base section to engage lthe outer surfaces of the base section ofthe whereby the cover section is wholly outside thebase section and thesides of the cover section are located inwardly from both sides of thebase section.

In testimony whereof I have signed my name to this speciication in thepresence of two subscribing witnesses. x
